Abstract
Method for producing a surface of revolution of a clock or watch component comprising a step of machining, with a femtosecond laser beam, a first surface of the clock or watch component so as to obtain a second surface, in particular so as to obtain a second surface whose roughness Ra is less than 100 nm, or less than 70 nm, and then a tribofinishing step applied to the second surface so as to obtain the surface of revolution.

A method for producing a surface of revolution of a clock or watch component, the method comprising:
- machining, with a femtosecond laser beam, a first surface of the clock or watch component so as to obtain a second surface, and then
- performing tribofinishing applied to the second surface so as to obtain the surface of revolution.
A clock or watch component having a surface of revolution whose roughness Ra is less than or equal to 15 nm and whose breaking stress in shear is above 200 N·mm−2.
